16 children : 20 adults
yes
no
Answer:
No
Step-by-step explanation:
If product of mean = product of extreme, then ratios are equivalent.
18 : 12 :: 16:20
Product of mean = 12 * 16 = 192
Product of extreme = 18 * 20 = 360
Not equivalent ratios
Answer:
Step-by-step explanation:
B. Exactly 1/4
C. Exactly 3/4
D. More than 3/4
Using substitution method, the system of linear equations has no solution.
To determine the solution to the system of equations, we can use substitution method;
4x - 5y = 5 ...eq(i)
-0.08x + 0.10y = 0.10 ...eq(ii)
From equation (i)
4x - 5y = 5
let's make x the subject of formula;
4x = 5 + 5y
x = (5 + 5y) / 4 ...eq(iii)
Put eq(iii) into equ(ii)
-0.08[(5 + 5y)/4] + 0.10y = 0.10
(-2/5 - 2/5y)/4 + 0.10y = 0.10
y = no solution
Since y has no solution, this implies that the system of linear equations has no solution.
